Woo hoo! There's your ext4 superblock.
Use "gdisk /dev/md0" and create a partition starting at sector 2048 and
occupying the rest of the array. After you save that, you may need
"partprobe /dev/md0" to rescan it.
You'll probably end up with a device named something like /dev/md0p1.
The output of dmesg will likely show you the device name.
Use "fsck -n /dev/md0p1" to verify the filesystem, and if that has
relatively few errors, you may mount it and start making backups.
